Species

Veillonella parvula

Type Strain: Prevot Te 3, ATCC 10790 T, CCUG 5123 T, NCTC 11810 T

Description and significance

French biologist Adrein Veillon, whom the species is named after, first discovered the species in 1898. Veillonella parvula is a gram negative bacteria found in microenvironments of the human body, commonly described in human intestinal, oral and vaginal microflora. Despite being part of the Firmicutes phyla, majority of which are gram positive, Veillonella has a peculiar gram negative cell wall known of the Negativicutes class. V. parvula essentially anaerobic and auxotrophic; it is also lactate fermenting, cocci shaped and small in size at 0.3-0.5 μm.

Give a general description of the species (e.g. where/when was it first discovered, where is it commonly found, has it been cultured, functional role, type of bacterium [Gram+/-], morphology, etc.) and explain why it is important to study this microorganism. Examples of citations ^[1], ^[2]
